Interesting concept, poorly executed

Rating: 3/10 (14 June 2019)

The film tackles an interesting idea, but approaches it in a superficial way and fails to be at all interesting after the major plot twist (secret) is revealed. From then onwards it turned into a bad sci-fi movie with by-the-books action done much better in many other films.
Many performances in the film are good. Ewan McGregor and Scarlett Johansson worked well together, but were let down bad writing - particularly in the last half of the film.
What annoys me about this film is how much better it could have been if it had been written better and the plot did not deteriorate so quickly. It is competent, but still seems like a huge missed opportunity to make something great.
